SAFETY-RAZOR.

Specification of Letters Patent.

Patented Aug. 21, 191?.

Application filed February 23, 1916; Serial No. 79,822.

To all whom it may concern:

Be it known that I, DAVID E. TELA, a citizen of the United States,residing at the city of Los Angeles, county of Los Angeles, and State ofCalifornia, have invented new and useful Improvements in Safety-Razors,of which the following is a specification.

The principal object of this improvement is to provide a safety razor bymeans of which the operation of shaving can be performed with greatease, convenience and comfort and without obscuring from view thecutting edge of the razor.

Heretofore safety razors have been constructed of two general types, onehaving a handle projecting centrally at right angles fromthelongitudinal plane of the blade, and the other having a handleprojecting from the end of the blade and in alinement therewith. In thefirst construction it. frequently occurs that the operation of shavingincludes strokes both in the direction of the nap'of the beard and inthe reverse direction which is likely to bring the hand of the user insuch position as to obscure from the view of the person shaving himselfthe cutting edge of the razor.

With the second type it is found inconvenient to use the blade in bothdirections.

In the present invention I have produced a third type of safety razor inwhich the handle extends from the end of and aslant.

relative to the plafiof the blade and longitudinally thereof so that inthe operation of shaving oneself the blade may be moved in alldirections with great ease and convenience and without bringing the handof the user into position to prevent the user from seeing in the mirrorthe image of the cutting edge of the razor.

A further object is to provide a safety razor in which the blade has twocutting edges and the parts between the cutting edges on each side ofthe longitudinal line are angularly disposed as to each other and whichcan be easily and quickly positioned in the holder without flexing itand can be quickly removed therefrom without disassembling the partsthereof.

A further object is to provide a head and handle which will hold theblade firmly and the parts of which can be easily and quickly assembledand can be easily and quickly cleaned without disassembling the parts.

Other objects will further appear from the description of the parts. Inthe drawings forming a part hereof:

Figure 1 is an enlarged central longitudinal section of my improvedsafety razor.

Fig. 2 is a side elevation of the upper end P thereof.

Fig. 3 is a rear end view of the blade holder.

FFig. 4 is a section on the line 4.4 of 1g. a

Fig. 5 is an enlarged end view of the blade viewed from the open end.

Referring to the drawings 10 is a clamp provided with a shank 11 whichprojects from near one end thereof at an angle substantially 135 degreesto the longitudinal plane of the clamp. The lower end of shank 11 isexternally screw threaded. 12 is a head which is provided with guardfingers 13 all of which fingers except one at each end are-cut away intheir upper surfaces ex cept at the points thereof so as to be clear. ofthe shaving portions 14 and 14 of the blade when it is positioned foruse. Head 12 has a hollow shank 15 which forms the handle of the razor.Shank 15 surrounds shank 11 and at the upper end is in sliding butnon-revoluble contact therewith. In the lower portion the two shanks areseparated. Near the lower end of shank 15 a portion of the internalsurface thereof is screwthreaded, the threads being cut reversely as tothe I the threaded portion of shank 15 when theparts are assembled foruse. Screw 16 is also internally threaded and engages the threadedortion of shank 11. Screw 16 has a shank 1 with a milled head 18 bymeans of which it is rotated to cause the clamp 10 to approach head 12or to move away from said head. Head 12 and clamp 10 form a bladeholder.

In order to keep the shank 11 and the tubular handle part 15 inoperative connection with the screw shank 17 and so that it will beimpossible to get these parts discon nected accidentally the threads onthe outer side of the screws are made longer than the length necessaryfor the actual operation so that when the holder is clamped the screwsare still in engagement with each other. The screw end of the shank 17is threaded a corresponding length and nected in the same way byscrewing that portion of the shank in advance into the screw. 1

The blade is preferably U-shaped and when positioned for use the membersof the blade straddle the shank of the upper clamp. I prefer to make theblade of the shape shown in Fig. 5 which shows the cutting edge portions14 and 14: of the blade triangular in cross section. is bent to bringthe portions 14. and 14 to lie in contact with the head without beingflexed. This brings the portions between the cutting edges and dinalline angularly disposed as to each other. The upper surface of the head,transversely, projects toward the central longitudinal line on straightlines which slope upwardly to their meeting point at the angle at whicha razor is usually held on the face when shaving. The lower surface ofthe clamp is of a shape to fit upon the blade so that it is held firmlywhen positioned for use without flexing it.

' By this construction it will be observed that after the operator hasshaved he can easily and quickly cause the clamp to separate far enoughfrom the head to remove the blade and for cleansing purposes, withoutthe clamp and head and handle being disengaged.

It will be observed that my razor blade is manufactured to the shaperequired for shaving and that it is positioned on the head withoutflexing and is held by the clamp in the correct position without itsbeing flexed. i

It will be observed that the U-shaped blade enables me to detach theblade without causing the other parts to become detached. Projecting thehandle from one end of the head at an angle to the longitudinal planeline of the head enables the user to see the face at the contact pointbetween the blade and the face when shaving.

The features of my device will facilitate the convenience of theoperator. The double action screw facilitates quick action for openingor closing the holder and great benefit is obtained from the simple formof the parts by means of which all parts of the holder can be kept inactual operative connection with each other, but can be de- 16, but itcan-be disconnected, when The .shank 14c the central longitushank ofsaid clamp of January, 1916.

" gaaaspco tentionfrom the operator, just place it on the shank of the.clamp and it is positioned when the holder is clamped. The angle atwhich the handle is secured to the holder gives greaterliberties to thehand to manipulate the device to greater advantage.

. While I have shown what I believe to be the preferred form of myinvention I do not wish to be limited to the precise details of thisconstruction, as it is obvious and appreciable that the parts andcombination of parts may be changed and varied within a wide range andstill embody the principles of the invention.

Having described myinvention what I claim is:

A safety razor, including a blade-holder comprising a clamp with adiagonally upwardly extending portion and a downwardly extending portionor shank, said shank projecting from near one end of said clamp at agiven angle to the longitudinal plane thereof, the lower end of saidshank being screw-threaded, a head having guardfingers, and a tubularshank receiving the and having a slidable but non-rotatable connectiontherewith, the upper surface of said head projecting transversely withrespect to the central longitudinal line thereof in right lines slopingupwardly to the apex-point, the same being the angle at which a razor isusually held upon the face for shaving, the lower surface of said clampconforming to the blade as against the flexing of the blade, and atubular externally screw-threaded member telescoping, and threaded intothe lower end of the shank of said head, the lower portion of" the shankof the clamp having a screw-threaded connection with said externallyscrew-threaded tubular member, the threads of the screw of said shank ofsaid head being of a different pitch from that of the threads of thescrew of shank of said clamp and of lesser axial extent.

- In witness that I claim the foregoing I have hereunto subscribed byname this day DAVID E. TELA.
